WITNESSES ATTORN EY Patented July 19, 11932 BERTRAM NIELSEN, OF SEATTLE, WASHINGTQN MILK `AND GREAM CAN COVER Y Application filed October 14,1829. Serial No. 399,563.

My invention relates to improvements in can covers, and more particularly to can covers used on milk and cream cans and cans of similar nature, and consists in the combiandv arrangements nations, constructions herein described and claimed. Y

An obj ect of my invention is to provide a can cover of the type described which isreadily mountable and demountable on the milk and cream cans now in conventional use.

A further object of my invention is to 'provide a locking attachment for my cov-er which is adapted to be readily fitted to cans of this nature of conventional construction.

A further object of my invention is to provide a cover for a milk or cream can that will prevent contact between the milk and cream in said cans and the engaging surfaces of said can and said cover whereby the milk is kept from becoming what is known in the tra-de as metallic, due to the presence of metal particles becoming suspended in said milk or cream due to the frictional sliding engagement of the surfaces of the neck of 3' the can and its cover.

A further obj ect of my inventionis to provide a cover for milk andfcream cans which will relieve the neck of said cans from strains and stresses encountered when the cans are stacked, thereby preventing the telescoping j of the neck of said cans.

A further object of my invention is to provide a can cover that will prevent the contents of the can from splashing therefrom.

A further object of my invention is to provide a can cover that will prevent the entrance of foreign matter into the can when closed.

A further object of my invention is to pro Vide a device of the type described which is simple in construction, has few parts and is not likely to get out of order easily. y

Other objects and advantageswill appear in the following specifica-tion and the novel features of theinvention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing, forming part of this application, in which: v

Figure 1 is a sectional elevational view of `'my invention, with parts thereof shown in elevation; and

Figure 2 is a sectional view, on line 2-2 of Figure'l. j

Tn carrying out my invention I make use of an ordinary milk can generally designated at 1 and having a neck of conventional form generally shown at 2. As is" well known in the trade these milk cans are provided with the sloping shoulder portions 3 at the base of said neck, and beaded or flanged'portions l adjacent the mouththereof.

For mounting my cover 5in locked position about said neck 2, l providean annulus or locking collar member 6 adapted to be pressed over the neck of a milk or creamcan of conventional form. As is seen fromV an examination of Figure 1 this locking collar is held in fixed relation to said neck 2 by means'of bead 4 which maybe spread Yinto engagement with the end thereof as shown at 7. The lower portion of this collar is flared outwardly forming an annular flange 8 adapted to engage the shoulder portion 3 and provided with staple members 9 for a purpose soon to be described.

My cover 5 having the bead 10 comprises a cylindrical portion 11`adapted to engage the outside -surfaceyof locking collar 6 and provided with a flared portion or annular flanged portion 12 adjacent the base thereof for engagement with the flanged portion 8 of the locking collar 6, asshown in Figure 1. This annular flanged portion 12 is provided with suitably formed slotsl properly positioned for engagement with the staple members 9. As tshown in Figure 1 these staple members 9 project through the slots 13 and above the flangedl portions 12 fora reason that will presently appear. This cylindrical portion 11 of my cover is enlarged adjacent the upper end thereon, as shown at 14, for'thefpurpose of adding strength to my structure ait this point.V Integral with theV cylindrical portion 11 is a cap member 15 connected with said cylindrical portion 11 at lits enlarged end-14. This cap portion is of inverted conical shape having the apex of the `cone projecting inwardly and positionedin the lateral center of they neck Vof the cone,

i rious parts of the device,`the operation'thereof may be readily understood. This cover as has been heretofore set forth is designed for use on milk cans of conventional design.

c lVhen it is desired to adapt this coverto milk cans of the type described the locking collar 6 is pressed over the neck 2 of said can and the bead 4 spread over lthe end of saidlocking collar, as shown at 4. The coveristhen fplaced overthe flocking collar with the slots jlltherein engaging-the staples 9 of said locking collar in a manner easily understood'. Suit-ablelocking meansof any nature, either conventional locks, wires, etc. may be then operatively-engaged with said staple members 9 securing the cover in locked relation to the can. l/Vhen it is desired to remove the cover it is merely necessary toremovefsai'd locking meansvand withdraw the cover from U. said-neck. ADue to the specially formed construction of the cap piece of my cover the downwardly projecting center thereof 16 will act as a baille plate for the liquid contained in the can, preventing the same from splashing as in ordinary cans. In the event that some of the'liquid seeps between the `bead t at the mouth of the neck of the can andmy cover it will notl carry the metallic 'particles occasioned by the frictional engagement of my cover with the walls of the locking collar into solution with the-liquid in the can.

It is further seen that lwhen packed the forces exerted on'the cover due-thereto will be distributed along the shoulder'B of the can `and not be transmitted through the neck of the can tothe joint of the neck with said can with consequent increased liability of break- 'ing said connection and-telescoping the neck within its can. I

collar for securing said cover in fixed position.

2. In amilk can, in combination, a collar having a cylindrical portion engaging the outside wall of the neck of a can, and a ianged portion engaging the shoulder of the can adjacent the base of said neck, a cover engaging about said collar, means for securing said collar to said can, and means for securing said cover to said collar.

3. In a milk can, `in combination, a collar Y surrounding the neck of said can and a shoulder adjacent the base of said neck, and having upwardly project-ing locking means thereon,'ac'overhaving a cylindrical portion and an annular flanged portion adapted to engage about said collar, a conically shaped cap portion, and means for engaging said upwardly projecting 'locking means, whereby said cover is sealably engaged with said can, and the splashing of the contained'liquid is decreased.`

In combination, a milk can having a cylindrical neck and sloping shoulders, a collar secured to said neck and having an annular flange complemental to said shoulders,

means for securing said collar to said neck, v

of a length to project downwardly into said neck beyond the upper abutting surfaces of said neck and cover.

Itis also seen that due to the angular relationof the plurality of 'frictional engaging vsurfaces between my cover and the can the j liability of the entry offoreign matter from wall -or the neck of the can, an annular flanged portion adapted to engage the shoulder of the can adjacent the base of said neck, and locking ymeans for said cover compris- --ing .acollar adapted `to lfit between said neck and'said cover,=and means integral with ysaid
